Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a squeezing device and a squeezing method used when squeezing a liquid contained in an organic substance or an inorganic substance such as fruits, vegetables, meat, beans, mud and processed products thereof.
It is also used as a sampling method for analyzing liquid components.

[0002]

2. Description of the Related Art Conventionally, a cylindrical container having a plurality of small holes for discharging juice from the bottom, a pressing tool inserted into the container, and a handle for pressing the pressing tool in the container. Are available commercially. The juiced object is stored in the container of the juicer, and when the handle is operated and the pressing tool is pushed in, the juiced juice extracted from the object comes out. Most of the juice will come out of the bottom hole, but the juice that has passed through the gap between the pressing tool and the container may remain on the pressing tool.

Further, since the squeezed juice also contains solids, it is necessary to further filter when it is desired to collect only the fluid. In addition, when squeezing an object to be squeezed containing a material that retains a liquid in cells such as fish meat and raw meat, there is a problem that the squeezing efficiency is poor only by pressing with a pressing tool using a conventional squeezing machine. there were.

Further, there are commercially available filtration devices in which a sample is sucked into a syringe such as a syringe, and then a filter material is attached to the discharge port and the syringe is pushed. However, since it does not have a function of squeezing, it is necessary to perform squeezing and filtering in separate steps. was there.

The present invention solves the above-mentioned drawbacks of the prior art, proposes a squeezing device that can perform squeezing and filtering at the same time without discharging the squeezing liquid onto a pressing tool, and also about a squeezing method. It proposes, in particular, a method of squeezing a squeezed object containing a material holding a liquid in a cell membrane, such as fish meat and raw meat.

[0006]

[Means for Solving the Problems] The inventors of the present invention have addressed the above-mentioned problems. If there is no gap between the cylindrical container of the conventional juice extractor and the outer circumference of the pressing tool, the pressing solution will not come on the pressing tool. It is possible to squeeze and filter at the same time by closing the outlet of the squeezed juice with a filter material, and it is possible to easily squeeze the object containing protein such as fish meat and raw meat by heat treatment before squeezing. That is, the present invention has been completed.

That is, claim 1 of the present invention is a squeezing device, which comprises a cylindrical container having a hole for discharging the squeezed liquid on the bottom surface, a pressing tool inserted into the container, and a means for pressing the pressing tool. The juice container is characterized in that a flexible material that slides in contact with the inner wall of the cylindrical container is provided on the outer circumference of the pressing tool.

Further, a preferred embodiment of the present invention is characterized by comprising a flexible sheet which is in contact with the lower surface of the pressing tool and has an outer diameter larger than the inner diameter of the container. Another preferred embodiment of the present invention is characterized in that the thickness of the flexible material according to claim 1 is reduced when the pressing tool is inserted into the container.

Further, a preferred embodiment of the present invention is characterized in that the bottom of the cylindrical container is provided with a filter medium. Further, a preferred embodiment of the present invention is characterized by including a manual handle for pressing the pressing tool.

The present invention is also a squeezing method, which is characterized in that the sample to be tested is stored in the cylindrical container of the present invention and squeezed by pushing a rear pressing tool. Furthermore, it is characterized in that the object to be squeezed is heat-treated before squeezing.

[0011]

According to the juicer of the present invention, when the pressing tool is inserted into the cylinder, the inner circumference of the cylinder is closed, so that the juice is not discharged onto the pressing tool and the juice can be efficiently extracted. Further, by providing a filter material at the outlet of the juice, it becomes possible to perform filtration simultaneously with the juice. Since filtration can be performed while applying pressure during filtration, the filtration efficiency is good. By providing a handle for pressing the pressing tool, squeezing and filtering can be easily performed manually.

Further, according to the squeezing method of the present invention, the squeezed object that can be squeezed efficiently and that holds the liquid in the cells, for example, fish meat and raw meat of birds, pigs, cows, etc. You can squeeze meat juice efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail. The squeezing device of the present invention is a squeezing device equipped with a cylindrical container having a hole capable of discharging the squeezed liquid at the bottom, a pressing tool inserted into the container, and a means for pressing the pressing device. A flexible material that slides in contact with the inner wall of the cylindrical container is provided, but it is sufficient if the squeezed liquid does not come out between the inner circumference and the pressing tool, and it has an outer diameter larger than the inner diameter of the container in contact with the lower surface of the pressing tool. A flexible sheet may be provided, or the flexible material may slide while reducing the thickness.

It is sufficient that the above-mentioned sheet bends when inserted in a cylindrical container and adheres to the inner wall of the container so as not to let the juice escape upward, rubber such as silicon, urethane and chloroprene, plastic such as soft vinyl chloride and tetrafluoroethylene. It can be selected from materials having equal flexibility. In addition to the above-mentioned sheet, the shape of the flexible material may be an O-ring fitted to the outer periphery of the pressing tool, or the flexible sheet may be inserted to reduce the thickness of the rear sheet.

The means for pressing the pressing tool is not limited as long as the purpose of squeezing is achieved, but various pressing methods such as manual pressing using a lever and pressing by pneumatic pressure or hydraulic pressure can be used.

Although the present invention also proposes to provide a filter medium on the bottom of the cylindrical container, the present invention enables simultaneous filtration with juice. The filter material may be selected from usual dialysis, membrane filtration, thickness filtration or a combination thereof depending on the purpose. The bottom does not necessarily mean a flat bottom and may be a bottom including a cylindrical portion, and the cylindrical portion may be provided with a filter medium. If filtration is performed using the cylindrical portion as well, the filtration area can be increased more than only the bottom surface, and clogging due to filtration can be alleviated.

Further, the filter medium may be arranged so as to close the hole for discharging the juice, but the bottom may be formed of the filter medium. A finer filter medium may be stacked on the bottom formed of the filter medium. The shape may be such that a cylinder formed of a filter medium at the lower end of a cylinder having no holes and a flat bottom formed of a flat filter medium at the lower end thereof may be sequentially formed by welding or molding. In that case, the bottom also serves as a filter medium and it is necessary to withstand pressing, so it is preferable to form it with a hard material such as ceramic, metal or plastic. As described above, the holes at the bottom are not necessarily round holes but may be a net or a filter medium.
